Kinetics of barite reduction from refractory barite-sulphide ore [PDF]

open access: yesMetallurgical and Materials Engineering, 2016
Refractory sulphide–barite ore was reduced with carbon in order to release lead, zinc, and copper sulphide from barite-pyrite base. Mineralogical investigations showed that due to the complex structural-textural relationships of lead, copper and zinc minerals with gangue minerals, it is not possible to enrich the ore using the conventional methods of ...
